Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Please refer to Figures 1-7, the utility model provides a technical solution:

A gantry-type submerged arc welding machine comprises a frame body slidingly connected with a support frame and its upper part, a welding machine is fixedly connected at the lower end of the frame body, a bearing plate is rotatably connected inside the support frame, and a fixing rod and a welding wire are fixedly connected at the lower end of the welding machine. One side of the rod is rotatably connected with a roller, and the outer wall of the roller is fixedly connected with several groups of touch rods, the other side of the fixed rod is fixedly connected with a connecting piece, the interior of the connecting piece is slidably connected with a cleaning rod, and the bottom of the cleaning rod is rotatably connected with two sets of cleaning sheets , An elastic sheet is fixedly connected between the cleaning rod and the cleaning sheet.

When using: The H-beam is placed on the support frame and the load-bearing plate, and then the welding wire is aligned with the position of the welding seam. At this time, the frame body drives the welding machine to move on the support frame, and the fixing rod is located at the back of the welding machine's recovery pipe. , at this time, the roller is in contact with the surface of the H-beam and rotates with the movement of the welding machine. After the recovery pipe recovers the excess flux, the rotation of the roller drives the touch rod to make intermittent contact with the cleaning rod. The contact between the rotating force and the cleaning rod makes the cleaning rod slide back and forth inside the connector, and the back and forth friction cleaning of the welding seam position is realized through the reciprocating process, so that the residue attached to the welding seam position is cleaned up, and the cleaning rod is The moving of the welding machine replaces the manual cleaning method, which reduces the labor intensity and improves the cleaning efficiency. The rotating connected bearing plate can also adjust the inclination angle, and the bearing plate can be rotated to the horizontal position. Welding is performed to improve practicability. Under normal conditions, the cleaning sheet is in a horizontal state under the elastic action of the elastic sheet, while the H-beam welding is placed obliquely, and the angle between the two side walls to be welded is 90 degrees. When it is moved down to the inside of the H-beam for welding, the cleaning sheet will be folded in the middle by the extrusion of the H-beam, from the flat state to 90 degrees that fit the two side walls of the H-beam. At this time, the two sets of elastic sheets are in their own Under the action of elasticity, it will resist the cleaning sheet, so that the cleaning sheet can clean the welding seam position, which is convenient for cleaning flat steel under normal conditions.

When the welding machine moves down to the inside of the H-beam for welding, the surface of the roller and the bearing plate is connected. Contact, when welding moves along the H-beam, the friction between the roller and the bearing plate drives the roller to rotate. During the rotation of the roller, the touch bar on the side wall is constantly in contact with the arc block. A driving force is generated on the arc block to drive the sliding block to slide inside the connecting piece, so as to realize the cleaning of the welding seam position by the cleaning rod.

A first spring is fixedly connected inside the connecting piece, and one end of the first spring is fixedly connected with the slider. When the space between the arc-shaped blocks is rotated to fit with the arc-shaped blocks, the arc-shaped blocks are moved under the action of the first spring. retracted, so that the arc-shaped block and the supporting plate connected with it generate a reciprocating motion during the overall forward movement.

The cleaning rod includes a connecting piece that is slidably connected between the support plate and the support plate, a second spring is fixedly connected between the connecting piece and the support plate, the elastic piece is fixedly connected between the connecting piece and the cleaning piece, and the cleaning piece is connected to the H-beam. When in contact, the connecting piece is pressed against the second spring, and the second spring contracts elastically. With the movement of the welding machine, when the cleaning piece cleans the residue on the H-beam, the second spring will be under the action of its own elastic force. Resist the connecting piece, so that the cleaning piece is resisted, and the effect is better when cleaning the residue.

Among them, a cleaning iron brush is fixedly connected to the lower end of the cleaning piece, and the touch rod is a round rod. The process of simulating manual reciprocating cleaning is realized by cleaning the iron brush, thereby improving the cleaning effect and efficiency. Reduce friction when blocks are in contact.

Among them, the upper end of the support frame is fixedly connected with a hydraulic rod, and the upper end of the hydraulic rod is rotatably connected with the bearing plate. When the angle of the support frame is adjusted, the hydraulic rod is activated, and the hydraulic rod rises to drive the bearing plate to rise. When the bearing plate is in a horizontal position, the The flat steel is welded, and during welding, the elastic sheet resists the cleaning sheet, so that the cleaning sheet is in a horizontal state, which is suitable for the cleaning work of the flat steel after welding.
